Question

A person can pay $15 for a membership to the science museum and then go to the museum for just $6 per visit. What is the maximum number of visits a member of the science museum can make for a total cost of $39?

Answer 1

We have the following:

`y=15+6x`

solving for x, when y is 39:

`\begin{gathered} 39=15+6x \\ 6x=39-15 \\ x=(24)/(6) \\ x=4 \end{gathered}`

Therefore, the maximum number of visits is 4 times
